sex changer ⇝

gender mender

(Or "gender bender", "gender blender", "sex
changer", and even "homosexual adaptor") A cable connector
shell with either two male or two female connectors on it,
used to correct the mismatches that result when some loser
didn't understand the EIA-232C specification and the
distinction between DTE and DCE. Used especially for
EIA-232C parts in either the original D-25 or the IBM PC's
D-9 connector.

There appears to be some confusion as to whether a "male
homosexual adaptor" has pins on both sides (is doubly male) or
sockets on both sides (connects two males).
